VS

GeForce GTX 295 vs GeForce GTX 980

Intro

The GeForce GTX 295 comes with clock speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 memory. It features 240 SPUs as well as 80 Texture Address Units and 28 ROPs.

Compare all that to the GeForce GTX 980, which has core clock speeds of 1126 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 2048 SPUs along with 128 TAUs and 64 Rasterization Operator Units.

As far as performance goes, the GeForce GTX 980 should in theory be just a bit better than the GeForce GTX 295 in general. (explain)

GeForce GTX 980 224000 MB/sec
GeForce GTX 295 223776 MB/sec
Difference: 224 (0%)

Texel Rate

The GeForce GTX 980 will be quite a bit (about 56%) more effective at anisotropic filtering than the GeForce GTX 295. (explain)

GeForce GTX 980 144128 Mtexels/sec
GeForce GTX 295 92160 Mtexels/sec
Difference: 51968 (56%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 980 is a better choice, by a large margin. (explain)

GeForce GTX 980 72064 Mpixels/sec
GeForce GTX 295 32256 Mpixels/sec
Difference: 39808 (123%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
